Slate can be made into roofing slate, a type of roof tile which are installed by a slater. Slate has two lines of ...
A model of the subducting Farallon slab under North America. In geology, the slab is a significant constituent of subduction zones. [1] Subduction slabs drive plate tectonics by pulling along the lithosphere to which they attach in a process known as slab pull and by inducing currents in the mantle via slab suction. [2]
Tile was also manufactured in a series of graduated wedge shapes for installation between steel members as a fireproof flat arch floor structure, to be covered with a concrete wearing surface above. In other cases, structural clay tile was used as a permanent form material to reduce the bulk and weight of structural concrete floor slabs. [8]
The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3–3/4 the thickness of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs.
The video game Minecraft released a version of Minesweeper in its 2015 April Fool's update. [13] The HP-48G graphing calculator includes a variant called "Minehunt", where the player has to move safely from one corner of the playfield to the other. The only clues given are how many mines are in the squares surrounding the player's current ...
Cement tiles are not fired; there is no glaze layer on the surface of the tile. They derive their durability from the combination of finely dehydrated ground Portland cement layer and a coarser layer of sand and cement. The pigment layer is hydraulically pressed into the surface and becomes a part of the tile.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
LI-900 is a type of reusable surface insulation tile developed and manufactured by Lockheed Missiles and Space Company in Sunnyvale, California. It was designed for use on the Space Shuttle orbiter as part of its thermal protection system to minimize thermal conductivity while providing maximum thermal shock resistance.
